Class: question_state - X-Ref
An enumeration representing the states a question can be in after a{@link question_attempt_step}.
There are also some useful methods for testing and manipulating states.
| __construct() X-Ref |
| No description |
| init() X-Ref |
| No description |
| get_all() X-Ref |
| Get all the states in an array. return: question_state[] of question_state objects. |
| get_all_for_summary_state($summarystate) X-Ref |
| Get all the states in an array. param: string $summarystate one of the four summary states return: array of the corresponding states. |
| __toString() X-Ref |
return: string convert this state to a string. |
| get(string $name) X-Ref |
| Get the instance of this class for a given state name. param: string $name a state name. return: question_state|null the state with that name. (Null only in an exceptional case.) |
| is_active() X-Ref |
| Is this state one of the ones that mean the question attempt is in progress? That is, started, but no finished. return: bool |
| is_finished() X-Ref |
| Is this state one of the ones that mean the question attempt is finished? That is, no further interaction possible, apart from manual grading. return: bool |
| is_graded() X-Ref |
| Is this state one of the ones that mean the question attempt has been graded? return: bool |
| is_correct() X-Ref |
| Is this state one of the ones that mean the question attempt has been graded? return: bool |
| is_partially_correct() X-Ref |
| Is this state one of the ones that mean the question attempt has been graded? return: bool |
| is_incorrect() X-Ref |
| Is this state one of the ones that mean the question attempt has been graded? return: bool |
| is_gave_up() X-Ref |
| Is this state one of the ones that mean the question attempt has been graded? return: bool |
| is_commented() X-Ref |
| Is this state one of the ones that mean the question attempt has had a manual comment added? return: bool |
| get_summary_state() X-Ref |
| Each state can be categorised into one of four categories: inprogress, needsgrading, manuallygraded or autograded. return: string which category this state falls into. |
| graded_state_for_fraction($fraction) X-Ref |
| Return the appropriate graded state based on a fraction. That is 0 or less is $graded_incorrect, 1 is $graded_correct, otherwise it is $graded_partcorrect. Appropriate allowance is made for rounding float values. param: number $fraction the grade, on the fraction scale. return: question_state one of the state constants. |
| manually_graded_state_for_fraction($fraction) X-Ref |
| Return the appropriate manually graded state based on a fraction. That is 0 or less is $manually_graded_incorrect, 1 is $manually_graded_correct, otherwise it is $manually_graded_partcorrect. Appropriate allowance is made for rounding float values. param: number $fraction the grade, on the fraction scale. return: int one of the state constants. |
| corresponding_commented_state($fraction) X-Ref |
| Compute an appropriate state to move to after a manual comment has been added to this state. param: number $fraction the manual grade (if any) on the fraction scale. return: int the new state. |
| get_feedback_class() X-Ref |
| Return an appropriate CSS class name ''/'correct'/'partiallycorrect'/'incorrect', for a state. return: string |
| default_string($showcorrectness) X-Ref |
| The result of doing get_string on the result of {@link get_state_class()}. param: bool $showcorrectness Whether right/partial/wrong states should return: string a string from the lang pack that can be used in the UI. |
